The idea is this the following:

An object is deleted if all the ptrs that point to it expired.

Each ptr has an age.

When a ptr releases an object, it checks if the object has any other ptrs 
with age older than the ptr. If not so, then it means the released ptr is 
the oldest one, and therefore the object should be deleted.

I have updated the Boost Vault files with an example with better unit 
testing.

It works, except when ownership of an object with cycles is transferred to a 
newer ptr.
